Functional cerebral asymmetry: a test of the selective activational model
… appear to substantiate a structural rather than activational model of functional cerebral asymmetries, but interference effects do unequivocally support either model. Furthermore, in Experiment 2, neutral faces were perceived as angry equally often in both visual fields, though neutral faces in …

Estradiol exerts activational and organizational control over the expression of daily and circadian activity rhythms in mice
… in a highly sex-dependent manner. Finally, activational estradiol strongly alters the transcriptional makeup within the SCN of female mice, primarily through message downregulation. Enriched molecular pathways in which estradiol decreased transcript expression of critical players include …

Sexual Behavior in Normal and Prenatally Androgenized Female Hamsters
… adult hormonal treatments are organizational or activational, this study tried to clarify whether male sexual behavior patterns exist in normal female hamsters free of any exogenous androgen treatments. When simply pairing the experimental female hamsters with estrous stimulus female hamsters …

Ovarian hormones, but not androgens, mediate running-induced changes in high fat diet choice patterns in rats
… results suggest that both organizational and activational effects of ovarian hormones play a role in female specific running-induced changes in diet choice patterns. Importantly, the activational effects of androgens are not required for the expression of HF diet avoidance in males.

Altered responsiveness to estrogens at estrogen receptor subtype 1 modifies the expression of circadian rhythms and daily activity patterns in mice
… 4). Finally, I confirmed the organizational and activational roles of estrogenic modification of circadian rhythms via an ESR1-mediated mechanism by looking at the expression of circadian behaviors with ESR1 over-expressing mice (EROE). I quantified the activity patterns of intact EROE male and …

Social, Emotional, Cognitive, and Physiological Correlates of Electronic Social Behavior
… appraisal, cognitive reappraisal, and activational control may have with electronic bullying and victimization. In Study 2, we used the Anxious Apprehension Model of Trauma to explore rejection cognitions as the mediator of the relationships among emotionality (emotionality, shame, …

Understanding female social dominance: comparative behavioral endocrinology in the Genus Eulemur
… of female dominance; 3) investigate the activational role of the sex-steroid hormones in adult female Eulemur using seasonal correlates of hormonal and behavioral change; and 4) examine the specific role of estrogen in the regulation and expression of sex-reversed female behavior in these …

Death by Frustration: How Defects in Cell Differentiation Trigger Apoptosis
… Since the net outcome between inhibitory and activational mechanisms ultimately determines a cell's fate, caspases and their regulation still continue to be subjects of intense study. Studies with dcp-1 described here have clarified its role as a Drosophila effector caspase. From the original …

Analyzing the Effects of Gonadal Hormones on Alcohol Seeking and Drinking in Alcohol-Preferring P Rats
… and males in each of the treatment groups. The activational effects of gonadal hormones may have a limited impact on alcohol-related behaviors in P rats, but more research is needed to make definitive conclusions about their role.

Investigation of the functions of Matrix Metalloproteinase-8 (MMP-8) in Mammary Carcinoma Cells
… chronic inflammation. This occurs through activational cleavage of a pro-inflammatory chemokine, Interleukin-8 (IL-8). Using an in vitro over-expression model it is shown in this thesis that MMP-8 reduced 2D random migration and scratch wound closure. It also increased cell adhesion and …
